[0074] In order to make the objectives, characteristics and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some of the embodiments of the present disclosure, but not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present disclosure.

[0075] In the following description, "some embodiments" are described, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0076] In the following description, the term "first\second" is only to distinguish similar objects, and does not represent a specific order of the object. It can be understood that "first\second" can be interchanged in a specific order or sequence as allowed, so that the embodiments of the present disclosure described herein can be implemented in an order other than that illustrated or described herein.

[0077] Unless otherwise defined, all technical and scientific terms used in the present disclosure have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. The terms used in the present disclosure are only for the purpose of describing the embodiments of the present disclosure, and are not intended to limit the present disclosure.

[0078] It should be understood that in various embodiments of the present disclosure, the size of the serial number of each implementation process does not mean the order of execution, and the execution order of each process should be determined by its function and inherent logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0079] When the server is running normally, a Basic Input Output System (BIOS) reports various fault information of the server to a BMC, and the BMC informs a user through a fault alarm lamp and a World Wide Web (Web) log. When the server is started, the BIOS delivers asset information of various devices (including a CPU, a memory, a hard disk, a network card, a Redundant Array of Independent Disks (Raid) card, etc.) identified in an initialization process to the BMC, so as to facilitate the BMC to display system information on the Web. During the server startup process, the BIOS performs initialization on all slot devices (i.e., slot devices), specifically, link training on the slot devices. After the training is successful, the BIOS can identify the slot device, and obtain asset information of the slot device by reading configuration space information of the slot device, and push the asset information to the BMC. However, due to various reasons such as poor slot contact, oxidation of a golden finger, signal interference, or abnormal slot device, etc., individual slot devices cannot complete link training in the initialization process, so the BIOS cannot identify the slot device, that is, a card loss phenomenon occurs. At this time, the BIOS cannot read the asset information of the slot device, and therefore cannot deliver the asset information to the BMC as part of the asset information. Since the BIOS cannot distinguish between the slot device card loss and the scenario that the slot is not inserted with a device, the BIOS cannot report the card loss fault in the startup process to the BMC for fault monitoring.

[0080] In the traditional scheme, some schemes ignore the fault alarm of the card loss scenario, and some schemes compare asset information received by the BMC with in-place information of the slot device determined by the BMC through a logic device, and determine, by the BMC, whether the number of the slot devices in the asset information sent by the BIOS is same as the number of the in-place information. If the numbers are different, the BMC actively triggers log recording of abnormal information, and lights up a corresponding system fault lamp to alarm.

[0081] However, in the above solution, on the one hand, it is heavily dependent on BMC, and if BMC is abnormal, the solution cannot work normally, and it is not applicable to workstations and other devices without BMC. On the other hand, the solution can only determine whether there is a card loss phenomenon, and cannot accurately determine the specific slot of the card loss device (i.e., the unrecognized slot device). Especially on a general server supporting multiple Riser cards and multiple configurations, quickly locating the card loss device is a problem that factory, user and operation and maintenance personnel pay great attention to. When the server is powered on in batches, it is difficult for the user to find the specific card loss device. Often, the operation and maintenance personnel need to locate the specific faulty device by manually plugging in and out the device, cross-verification or analysis by grabbing logs, which is low in efficiency and easy to misjudge. Therefore, how to accurately locate the slot of the training failed slot device for the server with flexible configuration is also a problem to be solved by the present disclosure.

[0082] Therefore, an embodiment of the present disclosure provides a data processing method. By standardizing the Riser hardware topology and design specification, a complete set of slot device silk screen acquisition solution and accurate alarm solution are formulated. The BIOS independently detects and judges the training failed slot device and its slot information, and then reports the training failed slot device slot information to the BMC and the OS, thereby realizing the function of accurately locating the slot of the card loss device, enriching the alarm approach and improving the fault locating efficiency.

[0083] Figure 1 A first optional flowchart of the data processing method provided by an embodiment of the present disclosure is shown, which will be described according to each step.

[0084] In step S101, based on the board card identifier of each riser card, the area and model of the server where each riser card is located are determined.

[0085] In some embodiments, a carrier (hereinafter referred to as the carrier) implementing the data processing method acquires the board card identifier of each riser card on the server, and determines the area of the server where each riser card is located and the model of each riser card based on the board card identifier.

[0086] In some embodiments, the area of the server where each riser card is located includes the installation area of each riser card on the server, which is usually A zone or B zone.

[0087] Wherein, the board card identifier corresponding to the same riser card is different when the riser card is located in different areas of the server; and the board card identifiers corresponding to riser cards of different models are different.

[0088] In some embodiments, the carrier can be a computer program, an electronic circuit, a database, a mobile application, an electronic device, a cloud computing platform, a distributed system, an artificial intelligence framework, a mathematical model, an automation tool and a microcontroller, etc., which can realize software or hardware of algorithm and method flow.

[0089] Step S102, based on the area and model of the server where each adapter card is located, traversing the slots of each adapter card, determining the in-place level information of each slot of each adapter card.

[0090] In some embodiments, the carrier traverses each slot of each adapter card in each area according to the area of the server, and determines the in-place level information of all slots of all adapter cards on the server. The in-place level information is used to represent whether a slot device is connected to the slot when the in-place level information of the slot is confirmed; if a slot device is connected to the slot, the in-place level information of the slot is set to a first preset value; if a slot device is not connected to the slot, the in-place level information of the slot is set to a second preset value.

[0091] Step S103, based on the physical link of each slot of each adapter card, determining the device unique identifier of the slot device connected to the corresponding slot.

[0092] In some embodiments, the carrier determines the physical link of each slot; the physical link includes the central processor identifier, port identifier and channel identifier connected to each slot.

[0093] In some embodiments, the carrier determines the physical link of each slot device based on the topology of all slot devices.

[0094] In some embodiments, the carrier determines the device unique identifier of each slot device, which includes at least one of bus identifier, slot device identifier and function identifier; if the device unique identifier includes bus (BUS) identifier, slot device identifier (Device) and function (Function) identifier, the device unique identifier is BDF, which is the logical address of the slot device.

[0095] In some embodiments, since the physical link of the connected slot and the slot device is the same, the carrier can associate the slot with the slot device based on the physical link, and further associate the slot with the device unique identifier of the corresponding slot device.

[0096] Step S104, based on the in-place level information of the slot and the device unique identifier corresponding to the slot, determining the slot device identification information.

[0097] In some embodiments, the carrier determines the identification information of the slot device connected to the slot based on the in-situ level information of the slot and the device unique identifier corresponding to the slot. Specifically, if the in-situ level information of the slot indicates that the slot device is not connected, the corresponding device unique identifier is empty; if the in-situ level information of the slot indicates that the slot device is connected, the corresponding device unique identifier is not empty. If the in-situ level information of the slot indicates that the slot device is connected, but the corresponding device unique identifier is empty, it indicates that the slot device identification has a problem, i.e., the training fails.

[0098] In this way, by corresponding the slot and the slot device through the physical link, determining the slot device identification information based on the in-situ level information of the slot and the device unique identifier corresponding to the slot, when the slot device training failure fault phenomenon occurs in the process of powering on the server, the function of accurately positioning the card loss device slot and simultaneously reporting the baseboard management controller and operating system alarm can be realized, the problem that it is difficult to locate the card loss in the process of powering on the server in batches is solved, and the factory production personnel, users or maintenance personnel can be helped to quickly locate the specific components, so as to quickly locate the cause or replace the related equipment.

[0099] Figure 2 A second optional flowchart of the data processing method provided by the embodiments of the present disclosure is shown, which will be described according to each step.

[0100] In step S201, the correspondence between the identification and the in-situ level information of each slot is determined based on the in-situ level information of each slot of each adapter card and the slot identification of each slot.

[0101] In some embodiments, the carrier reads the values of the pins of the first chip to determine the board card identification of each adapter card, and determines the area and model of the server where each adapter card is located based on the board card identification of each adapter card. The board card identification of the same adapter card is different when the adapter card is located in different areas of the server, and the board card identification of different models of adapter cards is different. The first chip can be a 9555 chip.

[0102] In some embodiments, the carrier sequentially traverses at least one adapter card corresponding to each area of the server based on the area of the server where each adapter card is located, and traverses at least one slot of each adapter card corresponding to the area of the server based on the model of at least one adapter card corresponding to the area of any server to determine the in-situ level information of each slot.

[0103] In a specific implementation, the carrier opens an integrated circuit bus channel (I2C) of the arbitrary adapter card, scans integrated circuit bus addresses of each slot included in the arbitrary adapter card, obtains in-place level information of each slot based on the integrated circuit bus addresses of each slot included in the arbitrary adapter card, and determines connection information of each slot based on the in-place level information of each slot.

[0104] Specifically, if the in-place level information of the slot is a high level, the slot is connected to a slot device, and the in-place level information of the slot is set to a first preset value (which can be 1); or, if the in-place level information of the slot is a low level, the slot is not connected to a slot device, and the in-place level information of the slot is set to a second preset value (which can be 0).

[0105] In some embodiments, the carrier determines a correspondence between the slot identifier and the in-place level information of each slot of each adapter card based on the in-place level information of each slot of each adapter card and the slot identifier of each slot.

[0106] In step S202, a correspondence between the slot identifier and the device unique identifier of each slot is determined based on the slot identifier of each slot of each adapter card and the device unique identifier corresponding to each slot.

[0107] In some embodiments, the carrier determines a physical link of each slot of each adapter card; the physical link includes a central processing unit identifier, a port identifier, and a channel identifier connected to the slot; the carrier obtains a topology of all slot devices in response to a slot device enumeration phase of a basic input / output system; determines a physical link corresponding to each slot device based on the topology of the slot device; wherein the physical links of the connected slot and the slot device are the same; determines a device unique identifier of the slot device connected to each slot; and determines the device unique identifier corresponding to each slot based on the physical link of each slot, the physical link corresponding to each slot device, and the device unique identifier of the slot device.

[0108] In a specific implementation, the carrier accesses a second chip to obtain a physical link of each slot; wherein the second chip and the first chip are of the same model, and are both 9555 chips.

[0109] In a specific implementation, the carrier determines a correspondence between the slot and the slot device based on the physical link of each slot of each adapter card and the physical link corresponding to each slot device; and determines the device unique identifier corresponding to each slot based on the correspondence between the slot and the slot device and the device unique identifier of the slot device.

[0110] Further, the carrier determines the correspondence between the identification of each slot and the device unique identifier corresponding to each slot based on the identification of each slot of each adapter card.

[0111] In some embodiments, the carrier determines the correspondence between the slot identification, the in-place level and the device unique identifier based on the correspondence between the identification of each slot and the in-place level information, and the correspondence between the identification of each slot and the device unique identifier.

[0112] In step S203, the carrier determines the slot device identification information based on the in-place level information of the slot and the device unique identifier corresponding to the slot.

[0113] In some embodiments, the carrier determines the slot device identification information based on the correspondence between the slot identification, the in-place level and the device unique identifier.

[0114] In implementation, the carrier, in response to determining that the in-place level information of any slot is low based on the correspondence between the identification of each slot and the in-place level information, confirms that the slot device identification information of the slot is an unconnected slot device; or, in response to determining that the in-place level information of any slot is high based on the correspondence between the identification of each slot and the in-place level information, determines the slot device identification information based on the device unique identifier corresponding to the slot.

[0115] Further, the carrier, in response to determining that the device unique identifier corresponding to the slot does not exist based on the correspondence between the identification of each slot and the device unique identifier, confirms that the slot device identification information of the slot is that the slot has a slot device but is not identified; or, in response to determining that the device unique identifier corresponding to the slot exists based on the correspondence between the identification of each slot and the device unique identifier, confirms that the slot device identification information of the slot is that the slot has a slot device and can be identified.

[0116] In some optional embodiments, if it is confirmed that the slot device identification information of the slot is that the slot has a slot device but is not identified, the carrier can further send the slot identification of the slot to the baseboard management controller through an intelligent platform management interface, so that the baseboard management controller generates alarm information, and the alarm information includes at least one of the slot identification of the slot, the model of the corresponding adapter card, the area of the server where the corresponding adapter card is located, and the board card identification of the corresponding adapter card.

[0117] In some optional embodiments, the carrier can further add the slot device identification information of the corresponding slot in the code corresponding to the current use state of the slot based on the slot device identification information; wherein different slot device identification information corresponds to different slot device identification information.

[0118] For example, for the slot device that fails in training, the Unavailable field can be filled in the Current Usage field of the corresponding slot in the SMBIOS Table Type 9. For the slot device that can be normally identified, InUse is filled in the Current Usage field of the corresponding slot. For the unused slot, BIOS fills UnUse in the Current Usage field of the corresponding slot. Therefore, the user and the operation and maintenance engineer can manually check or screen the slot device training failure under the OS in batches.

[0119] In this way, by corresponding the slot with the slot device through the physical link, determining the slot device identification information based on the in-place level information of the slot and the unique identifier of the device corresponding to the slot, when the slot device training failure fault phenomenon occurs in the process of powering on the server, the function of accurately positioning the card loss device slot and simultaneously reporting the baseboard management controller and the operating system alarm is realized, the problem that it is difficult to locate the card loss in the process of powering on the server in batches is solved, and the factory production personnel, the user or the maintenance personnel are helped to quickly locate the specific component, so as to quickly locate the cause or replace the related device.

[0120] Figure 3 A third optional flowchart of a data processing method provided by the embodiment of the present disclosure is shown, which will be described according to each part.

[0121] In the related art, some manufacturers ignore the fault alarm problem of the slot device in the training failure scenario in the boot stage, and some manufacturers rely on BMC to obtain in-place information and combine the push asset information of BIOS to determine the slot device training failure scenario. On the one hand, the specific slot information of the training failure device cannot be accurately located, and on the other hand, it is seriously dependent on BMC and cannot be applied to workstations and other devices without BMC. When the server is powered on in batches and the card loss occurs, it brings unnecessary trouble to the factory, the user and the operation and maintenance personnel. In order to solve the current technical problems and provide better user experience for users, a method for detecting and accurately alarming the training failure of the slot device is very necessary. The embodiment of the present disclosure formulates the Riser hardware design specification, unifies the I2C topology of the Riser card, so that BIOS can independently and automatically identify the silk screen position, I2C topology, mapping relationship of BDF and Slot of each PCIeSlot slot, and then accurately locate the slot information of the card loss device and report it to BMC and OS.

[0122] In step S301, the correspondence between the slot and the in-place level information is determined.

[0123] In some embodiments, the server includes an A zone and a B zone, and each zone can be provided with a riser card. The carrier reads the board card identification (Board Id) of the riser card in sequence through I2C in the POST stage of the server power-on, that is, the riser card used by the A zone and the B zone of the server can be obtained. After confirming the riser cards used by the A zone and the B zone, the I2C channels of different slots of each riser card are opened in sequence, the I2C addresses of the slots are scanned, the in-place level information of different slots is read, and the scanning of all slots of all riser cards on the server is completed in sequence. The corresponding relationship between the slots and the in-place level information is created, that is, the set SlotPreVec is obtained.

[0124] In specific implementation, the carrier can jointly constitute a group of matrices with the identification (Slot Id) of each slot as the key (Key) and the in-place level information as the value (Value), which are filled into SlotPreVec in sequence, that is, the corresponding relationship between all slots and in-place level information is obtained.

[0125] In some embodiments, the carrier can be a BIOS.

[0126] Step S302, determining the corresponding relationship between the identification of the slot and the device unique identifier.

[0127] In some embodiments, after the carrier confirms the riser cards used by the A zone and the B zone, the second 9555 chip is accessed to obtain the physical link identification (MCIO ID) of each slot. The MCIO ID is used to represent which CPU (x) and which Port (y) and the start address (z) of the PCIe Lane are actually connected to the slot in the actual physical link; that is, the slot is actually connected to the xth CPU and the yth Port, and the start address of the PCIe Lane is z. Optionally, the physical link is defined as CPUx-PEy-LANEz, and the MCIO ID has a one-to-one correspondence with CPUx-PEy-LANEz.

[0128] In some embodiments, the carrier obtains the topology of all slot devices and the BDF (Bus, Device, Function) information of each slot device in the slot device enumeration phase. Through the topology of the slot device, it is located that each slot device is connected to which CPU (x) and Port (y) and the start address (z) of the PCIe Lane, that is, CPUx-PEy-LANEz. Since CPUx-PEy-LANEz has a one-to-one correspondence with the MCIO ID, that is, the slot and the physical link (or MCIO ID) of the connected slot device are the same, the carrier can obtain the MCIO ID of each slot device.

[0129] In some embodiments, the identification of the slot has a one-to-one correspondence with the MCIO ID, and the MCIO ID of the slot device has a one-to-one correspondence with the BDF of the slot device, so the identification of the slot and the BDF of the slot device can be associated through the MCIO ID to obtain the set SlotPcieMap.

[0130] In specific implementation, the carrier can determine the correspondence between the identification of the slot and the device unique identifier with the identification of the slot as the key (Key) and the BDF of the slot device as the value (Value), that is, the set SlotPcieMap.

[0131] In step S303, based on the correspondence between the slot and the in-place level information, and the correspondence between the identification of the slot and the device unique identifier, the identification of the slot whose training fails is determined.

[0132] In some embodiments, the carrier compares the set SlotPreVec and the set SlotPcieMap to determine the identification of the slot whose in-place level information is the first preset value but does not have a corresponding device unique identifier. The identification of the slot is the slot information of the slot device whose training fails. Training failure means that the slot is connected to the slot device, but the slot device cannot be identified.

[0133] In some embodiments, the carrier uploads the identification of the slot whose training fails to the BMC in the form of an event log. Optionally, the Unavailable field is filled in the Current Usage field corresponding to the slot in the SMBIOS Table Type 9.

[0134] Thus, by the data processing method provided by the embodiments of the present disclosure, for the case that multiple Riser cards need to be matched on the same server to support multiple configurations, the uniqueness of the server chassis Slot Id is closely followed, the Riser hardware design specification is formulated, and the I2C topology of the Riser is unified, so that the BIOS can automatically identify the silk screen position, I2C topology, mapping relationship between BDF and Slot of each PCIe Slot, and when the slot device training failure fault phenomenon occurs in the process of server power-on, the function of accurately positioning the card loss device slot and simultaneously reporting the BMC and OS alarm can be realized, the problem that it is difficult to locate the card loss in the process of server batch power-on is solved, the factory production personnel, users or maintenance personnel are helped to quickly locate the specific components, so as to quickly locate the cause or replace the related equipment. At the same time, the dependence on the BMC device in the traditional scheme is broken, and the application scenarios are more extensive.

[0135] Figure 4 A fourth optional flowchart of the data processing method provided by the embodiments of the present disclosure is shown, Figure 5 A schematic diagram of a slot device silk screen mapping table provided by the embodiments of the present disclosure is shown.

[0136] In step S401, the board card identifier of each adapter card is acquired.

[0137] In some embodiments, in the POST stage of server power-on, the carrier reads the board card identifier (Board Id) of each Riser card through I2C in sequence, that is, it can be acquired which Riser card is used in the A area and the B area of the server. As shown in Figure 5 When the Board Id is read as 0x01, it can be confirmed that the Riser card is Riser_0 and is inserted in the A area of the server. If the Board Id is read as 0x81, it can be confirmed that the Riser card is Riser_0 and is inserted in the B area of the server.

[0138] In some optional embodiments, the carrier can acquire the Board Id of each adapter card by reading the values of IO_0 to IO_7 of the first chip (PCA9555 chip). PCA9555 is a GPIO expansion chip, but in the embodiments of the present disclosure, the chip is not limited to be used for Board Id reading, and other ways such as CPLD, GPIO, FRU, etc. can also be used to acquire the Board Id.

[0139] In step S402, the in-place level information of each slot is determined.

[0140] In some embodiments, after the carrier confirms the Riser cards used by the A area and the B area respectively, the carrier accesses the I2 Switch chip on each Riser card, sequentially opens the I2C channels of different slots, scans the I2C addresses of each slot, respectively reads the in-place level signals of different slots, detects the physical in-place situation of all slots through high and low level signals, and sequentially completes the scanning and measurement of all slots on the server. As shown in Figure 5 The I2C channels of the three slots on the Riser card are 1, 2 and 3 in sequence. According to the in-place level signal (Present), 0 represents that there is no in-place device in the slot, and 1 represents that there is an in-place device in the slot.

[0141] Step S403: Determine the set corresponding to the identification of the slot and the in-place level information.

[0142] In some embodiments, the carrier reads the in-place level information of each slot, takes the Slot Id of each slot as the Key, and takes the in-place information as the Value to jointly form a set of elements, and sequentially fills in SlotPreVec, that is, the mapping set of all slots and in-place information is obtained. Slot Id is the silk screen information of the slot device in the server case, which has uniqueness.

[0143] Step S404: Determine the physical link of each slot.

[0144] In some embodiments, in the design of the server, the same slot in the same area of the mainboard can be inserted with different Riser cards, and the MCIO interface and the CPU can realize different configurations according to different MCIO cable connection modes. Therefore, different configurations of the same server are jointly determined by the model, insertion method and MCIO cable connection method of the Riser card.

[0145] In some embodiments, after the carrier confirms the Riser cards used by the A area and the B area respectively, the carrier needs to continue to access the second 9555 chip to obtain the MCIO ID of each slot and determine the source of the slot. MCIO ID is used to represent which CPU (x) and which Port (y) of the CPU (x) and the start address (z) of the PCIe Lane are actually connected in the actual physical link.

[0146] Specifically, there can be 1, 2, 4 or more CPUs on the server, each CPU has different Ports such as PE0 and PE1, and each Port has 16 PCIe Lanes. As shown in Figure 5 The physical link is defined as CPUx-PEy-LANEz, which has a one-to-one correspondence with the MCIO ID.

[0147] Optionally, according to the description, the same slot has the ability to have different connection methods, so the reserved design scheme has a one-to-many relationship between the Slot ID and the MCIO ID. However, after the server is assembled, the connection method of the same slot is fixed, and at this time, the Slot ID and the MCIO ID have a one-to-one correspondence.

[0148] Step S405, determine the device unique identifier of each slot device.

[0149] In some embodiments, the BIOS obtains the topology of all slot devices and the BDF information of each slot device in the slot device enumeration phase. Through the topology of the slot device, the carrier can locate which CPU (x) and which Port (y) of each slot device are connected to, as well as the start address (z) of the PCIe Lane, that is, CPUx-PEy-LANEz. Since CPUx-PEy-LANEz has a one-to-one correspondence with the MCIO ID, the BIOS can obtain the corresponding MCIO ID of each slot device.

[0150] Step S406, determine the correspondence between the identification of the slot and the device unique identifier.

[0151] In some embodiments, the carrier binds the device unique identifier of the slot device with the identification of the slot based on the set of the identification of the slot corresponding to the bit level information determined in step S403 and the physical link identifier of each slot device.

[0152] In specific implementation, a set of key-value pairs is formed with Slot Id as Key and slot device BDF information as Value, and a mapping set SlotPcieMap of the slot and device information is created and improved.

[0153] Step S407, determine the slot device identification information of each slot based on the set of the identification of the slot corresponding to the bit level information and the correspondence between the identification of the slot and the device unique identifier.

[0154] In some embodiments, the carrier can traverse the set SlotPreVec. When the obtained slot corresponds to in-place level information of 0, it indicates that there is no in-place slot device, the slot is not used, and the next element of SlotPreVec is continued to be traversed. When the obtained slot corresponds to in-place level information of 1, the Slot Id of the slot is taken, and based on the Slot Id of the slot, a search is performed in the set SlotPcieMap. If the BDF information of the slot device can be searched, it indicates that the slot device is normally identified, the slot and the slot device are ignored, and the next element of SlotPreVec is continued to be traversed. If it cannot be searched, it indicates that the slot has an in-place slot device, but is not normally identified, and a slot device training failure phenomenon occurs. That is, the Slot Id is the identification of the slot of the slot device with training failure.

[0155] Step S408, the identification of the slot with training failure is uploaded to the BMC.

[0156] In some embodiments, the carrier reports the identification of the slot of the device with training failure to the BMC in the form of event logs through IPMI. The BMC generates alarm information, displays the event log of training failure in the log of the Web interface, and clearly marks the slot number of the slot device with training failure in the event log, accurately informs the user of the position of the device with training failure. At the same time, the fault alarm lamp of the server lug is lit to visually inform the user.

[0157] Step S409, based on the slot device identification information, the slot device identification mark of the corresponding slot is added in the code corresponding to the current use state of the slot.

[0158] In some embodiments, for the identification of the slot with training failure, the carrier fills the Unavailable field in the Current Usage field of the corresponding slot in the SMBIOS Table Type 9. For normal devices, BIOS fills InUse in the Current Usage field of the corresponding slot. For unused slots, BIOS fills UnUse in the Current Usage field of the corresponding slot. Therefore, the user and the operation and maintenance engineer can manually check or screen the slot device training failure under OS.

[0159] Thus, by the data processing method provided by the embodiments of the present disclosure, for the case that multiple Riser cards need to be matched on the same server to support multiple configurations, the uniqueness of the server chassis Slot Id is closely followed, the Riser hardware design specification is formulated, and the I2C topology of the Riser is unified, so that the BIOS can automatically identify the silk screen position, I2C topology, mapping relationship between BDF and Slot of each PCIe Slot, and when the slot device training fails during the server power-on process, the function of accurately positioning the card loss device slot and simultaneously reporting the BMC and OS alarm can be realized, the problem that it is difficult to locate the card loss in the server batch power-on process is solved, and the factory production personnel, users or maintenance personnel can be quickly positioned to the specific components, so as to quickly locate the cause or replace the related equipment. At the same time, the traditional scheme is freed from the dependence on the BMC device, and the application scenarios are more extensive.
